WINGHAM, ONT. -- A person who attended a 'buck and doe' gathering in Seaforth on March 14, has tested positive for COVID-19.

The Waterloo Region Public Health Unit is asking anyone who was at the buck and doe on March 14 in Seaforth to self monitor for symptons until Sunday (14 days from the date of the event). If they develop symptoms they're asked to self isolate.

The health unit says it is unclear is the person contracted the virus before, during or after the event.

At the time of the celebration, gatherings of 250 people or less were still allowed by area health units.

The health unit is simply encouraging people who attended to self-isolate immediately.
